This is one of those shooters from the late 1990s that really drives home how the Quake Engine felt like two steps forward, one step back at the time. Yes, environments are full 3D, but everything feels claustrophobic and lifeless compared to the Doom Engine-based Hexen 1. The "puzzles" amount to simple key-hunting, nothing on the level of what N64 games were doing at the time. The result is a game that is merely "okay," not an enduring classic that is begging to be played over and over. It's good enough to be worth playing in order to peek into a corner of gaming history that nearly destroyed Raven Software due to its poor sales.
